C. S. Lewis on Mind

"I fancy that most people who think at all have done a great deal of their thinking in the first fourteen years."

"You could send your soul after the good you had expected, instead of turning it to the good you had got. You could refuse the real good; you could make the real fruit taste insipid by thinking of the other."

"There is wishful thinking in Hell as well as on Earth."

"The standard of permanent Christianity must be kept clear in our minds and it is against that standard that we must test all contemporary thought. In fact, we must at all costs not move with the times."

"A strict allegory is like a puzzle with a solution: a great romance is like a flower whose smell reminds you of something you can't quite place. I think the something is 'the whole quality of life as we actually experience it.'"

"If we are going to be destroyed by an atomic bomb, let that bomb when it comes find us doing sensible and human things — praying, working, teaching, reading, listening to music, bathing the children, playing tennis, chatting to our friends over a pint and a game of darts — not huddled together like frightened sheep and thinking about bombs. They might break our bodies but they need not dominate our minds."

"... in such a matter he would never have been guided by his first thoughts nor even by his twenty-first . Beyond doubt he would have prolonged deliberation till his hundred-and-first; and they would be infallibly and invincibly wrong. This is what always happens to the deliberations of a simple man who thinks he is a subtle one."

"If you read history you will find that the Christians who did most for the present world were just those who thought most of the next... It is since Christians have largely ceased to think of the other world that they have become so ineffective in this. Aim at Heaven and you will get earth "thrown in": aim at earth and you will get neither."

"He always sends errors into the world in pairs—pairs of opposites. And he always encourages us to spend a lot of time thinking which is the worse. You see why, of course? He relies on your extra dislike of the one error to draw you gradually into the opposite one. But do not let us be fooled. We have to keep our eyes on the goal and go straight through between both errors. We have no other concern than that with either of them."

"Wisdom: The first error is that of the southern people, and it consists in holding that these eastern and western places are real places. ... give no quarter to that thought, whether it threatens you with fear, or tempts you with hopes. For this is Superstition and all who believe it will come in the end to the swamps to the south and the jungles to the far south. Part of the same error is to think that the Landlord is a real man:"

"The man is a humbug — a vulgar, shallow, self-satisfied mind, absolutely inaccessible to the complexities and delicacies of the real world. He has the journalist's air of being a specialist in everything, of taking in all points of view and being always on the side of the angels: he merely annoys a reader who has the least experience of knowing things, of what knowing is like. There is not two pence worth of real thought or real nobility in him. But he isn't dull..."

"Suppose I think, after doing my accounts, that I have a large balance at the bank. And suppose you want to find out whether this belief of mine is “wishful thinking.” You can never come to any conclusion by examining my psychological condition. Your only chance of finding out is to sit down and work through the sum yourself. When you have checked my figures, then, and then only, will you know whether I have that balance or not. If you find my arithmetic correct, then no amount of vapouring about my psychological condition can be anything but a waste of time. If you find my arithmetic wrong, then it may be relevant to explain psychologically how I came to be so bad at my arithmetic, and the doctrine of the concealed wish will become relevant—but only after you have yourself done the sum and discovered me to be wrong on purely arithmetical grounds. It is the same with all thinking and all systems of thought. If you try to find out which are tainted by speculating about the wishes of the thinkers, you are merely making a fool of yourself. You must first find out on purely logical grounds which of them do, in fact, break down as arguments. Afterwards, if you like, go on and discover the psychological causes of the error."
